but in all of these three cases i encountered a problem that pressure distribution falls some blew vapor pressure . fore example if define the vapor pressure 3500 pascal, then when cavitation occure i get pressure about 2500 pascal in cavitation region.

hi
please chech outlet boundary(pressure outlet) and see gauge pressure and also oprational condition that were correctly opted and message from FLUENT
being successful

Dear all,

I modeled the three kinds of problem in cavitation mode in fluent:

1-2-D nozzele 2-2-D hydrofoil naca0015 3-3-D marine propeller

but in all of these three cases i encountered a problem that pressure distribution falls some blew vapor pressure . fore example if define the vapor pressure 3500 pascal, then when cavitation occure i get pressure about 2500 pascal in cavitation region.
